+ Description

As a great addition to your shower project, KBRS offers a variety of specialized accessories to maximize your shower enjoyment. Much like our shower pan, at KBRS our ShowerSeat™ also comes Ready-To-Tile. We offer a variety of seat shapes to fit your custom tile shower needs including a ladies leg ledge, corner, ready to tile shower seat and multiple ready to tile shower bench seats available in standard and custom widths. View All Shower Seats >

Made of solid 3-pound EPS block construction (the toughest in the industry), our lightweight seats easily install in just a few minutes. You'll maximize the enjoyment of your KBRS Shower System with a ShowerSeat™ that's the perfect fit for your new tile shower. Our high-density expanded polystyrene (EPS) ready to tile shower seats are especially strong, lightweight, and durable. The solid block construction eliminates the "void" created when using framing to construct a shower seat. By eliminating the "void", you eliminate any place for mold and mildew to grow.

Each ShowerSeat™ is coated with a protective elastomeric primer that allows any surface be applied. Tile is the most popular surfacing used; however, other decorative shower surfaces may be applied as desired. Solid Surface makes a great bench top.

All of the KBRS, Inc. ready to tile shower seats are quick and easy to install and require no framing. Simply attach the ready-made product with a commonly found modified thin-set, then apply your tile.

We can manufacture virtually any shape or size shower seat you require for your project, this includes radius options - if you can draw it, we can make it! Simply fill out a custom order form (below) and submit to our customer service department for a quote or to order.

Step 1:

Step 2:

Trowel modified thin-set throughout the marked area (from step 1) where the seat will be installed and on the sides and bottom of the ShowerSeat™. Firmly press the seat into place, then level.

Step 3:

Apply a generous bead of ShowerSeal® Polyurethane Sealant to seams of seat. Tool sealant smooth.

Step 4:

Apply ShowerSeal® Liquid Membrane to edges of seat, then embed Gauging Fabric into wet membrane. Smooth over any wrinkles or bubbles.

Step 5:

Coat over Gauging Fabric “sandwiching” the fabric into ShowerSeal® Liquid Membrane.

Step 6:

Allow ShowerSeal® Liquid Liner to dry, then apply a second coat. Allow time to dry, then apply thin-set and decorative surfacing.
